Title: Hydraulic buffer
Inventor: MORI NOBUO
IPC: F16F9/44
Filed: 1995-01-30
Abstract: PURPOSE: To reduce a friction coefficient between a select valve and the inner wall surface of a bypass passage by constituting the select valve by a thermoplastic low friction resin. CONSTITUTION: A rotary valve 43 is constituted by a thermoplastic and oil-proof low friction resin material. For example, polyamide, polyimide and polyamide imide are suitable. By such constitution, a friction coefficient between the rotary valve 43 and the inner wall surface of a bypass main flow passage 41 can be reduced. Especially, in the rotary valve 43, when the side peripheral surface of a base part 51 combined with the plate stopping part 49 of an operation rod 44 is formed in a taper shape whose diameter is shrunk in the direction of the operation rod 44, the friction coefficient can be reduced more.  Consequently, the operability of the rotary valve 43 can be made favorable by the operationn rod 44 without the interpose of a low friction member between the rotary valve 43 and the inner wall surface of the bypass main flow passage 41, in other words without an increase in the number of part items.

Title: Detecting apparatus abnormality of electrical wire
Inventor: SANAKA JUNICHI
IPC: H05K13/08
Filed: 1990-02-13
Abstract: PURPOSE:To improve efficiency for detecting abnormality of an electrical wire by generating laser light having a predetermined width in perpendicular and horizontal directions with respect to a tip of the electrical wire. CONSTITUTION:When an electrical wire whose defect is to be detected lowers to an approximate center of a turning table 2, if a hair-like part where a part 1b of a conductive wire has been bent is generated on a tip 1a of the electrical wire 1, laser light La having a predetermined width in a perpendicular direction is partially shielded to have a detected signal level of a light receiving part 3a of a first laser-type sensor varied so that an abnormality can be detected. On the other hand, the tip 1a of the electrical wire 1 partially shields laser light Lb having a predetermined width in a horizontal direction from second laser-type sensors 4a, 4b. In this case if a diameter of the whole conductive wire becomes large at the tip 1a due to looseness of the conductive wire or excessive application of solder, an amount of shielded laser light Lb varies. Thus a detected signal level of light receiving part 4a of the sensor varies to allow the abnormality to be detected.

Abstract: PURPOSE:To avoid the deterioration of characteristics and the development of defective bonding, by exposing the first and second insulation films by ion-milling of a multilayer metal, a photoresist, and the like, thereby removing selectively these insulation films by chemical etching. CONSTITUTION:A liquid where silicon compounds are dissolved is coated on a protecting film 12 located on a substrate 11 and the first insulation film 13 is formed by drying the protecting film coated with the above liquid. After removing the above film 13 selectively, a multilayer metal is deposited on the substrate and similarly in the case of the first insulation film 13, the liquid is coated on the multilayer metal and the second insulation film 17 is formed after drying its metal coated with the liquid. Then, a part forming an electrode for a pad is masked by a photoresist 18. After that, inactive ion beams are irradiated extensively in the form of shower to the above part to expose the first and second insulation films 13 and 17 by treating the second insulation film 17 except a part below a mask region, multilayer metal, and the photoresist 18 with an ion-milling process. Subsequently, these insulation films 13 and 17 are removed selectively by chemical etching. This approach avoids the deterioration of characteristics due to over-etching of the protecting film 12 and prevents the development of defective bonding because of sticking of the resist.
